Flipkart — Flipkart Axis Bank Credit Card have become a big headache for me

Address:

India

I have applied for Flipkart Axis Bank Credit Card through Flipkart, where is was showing No Annual Fee, No Joining Fee and Lifetime free credit card but due to technical glitch the bank have issued me the paid credit card and the same was accepted by the bank.
"We would also like to inform you that as per the bank's record you have applied for life time free credit card through Flipkart application but received chargeable credit card." As bank stated.
I have visited the Axis Bank Branch for the same, but didn't get solution even I have forwarded them multiple emails too but bank is claiming now that I have applied for chargeable credit card. When I visited the Axis Bank branch they said that only Flipkart can provide you the solution and when I contacted Flipkart, they are saying that only bank can provide you any solution. So I am totally stuck in their policies where I am completely helpless. Kindly help me that what should I do now.
